Professor T.

LOVED this until the final season. In many ways, the professor was a more quirky German version of Monk. As someone with ASD and PTSD, I could sympathize with many of his struggles. There were those who loved him and supported him, those who tolerated him, those who respected him, and those whom he annoyed beyond all belief. I realize that shows have to kill off characters for a variety of reasons. I won't be a spoiler and say who they are here. I also know that some shows need a definitive way to end a series. There are classic good ways of doing this like MASH and terrible ways like Seinfeld but this was the WORST EVER. After the final episode, I regret ever watching the show.
